Density functional theory calculation of the optical properties and topological analysis of the electron density of MBi2B 2O7 (M = Ca,Zn) compounds
(American Institute of Physics, 2013-02)
The topology of the electron density for congruent melting oxyborate Bi2ZnOB2O6 and CaBi2B 2O7 is studied in light of the theory of atoms in molecules. All the electron density critical points in the unit cell are ...
Bicolor laser stimulated elastooptical effect in the 2-cyclooctylamino-5-nitropyridine-C70 system
(Springer, 2013-01)
For the first time the piezooptical effect has been observed in the 2-cyclooctylamino-5-nitropyridine doped with intermolecular strong acceptor—fullerene C70. The observed effect may be used for optically operated ...
Influence of varying Germanium content on the optical function dispersion of Fe 2MnSi xGe 1-x: An ab initio study
(Elsevier B.V., 2013-01)
The optical dielectric functions of Fe 2MnSi 1-xGe x alloys for selected concentrations (x=0.0, 0.25, 0.5, 0.75 and 1.0) were investigated. The ferromagnetic Fe 2MnSi xGe 1-x is semiconducting with optical band gaps 0.507, ...
Electronic structure of quaternary chalcogenide Ag₂In₂Ge(Si)S₆ single crystals and the influence of replacing Ge by Si: Experimental X-ray photoelectron spectroscopy and X-ray diffraction studies and theoretical calculations
(American Scientific Publishers, 2013-04)
Ag₂In₂GeS₆ and Ag₂InSiS₆ are two interesting quaternary-sulfide single crystals. Starting from our previous investigation on Ag₂In₂GeS₆ single crystals, the Ag₂In₂SiS₆ is investigated here. We demonstrate the effect of ...
Calculation of the lattice constant of hexagonal compounds with two dimensional search of equation of state and with semilocal functionals a new package (2D-optimize)
(Elsevier B.V., 2013-04-05)
A new package for calculating lattice constants and equation of state for hexagonal and tetragonal structure is released. We call it as 2D-optimize. The new package is compatible with the highly accurate all-electron ...
Electrical behaviour of MEH-PPV based diode and transistor
(Elsevier Ltd., 2013-11)
The potential of organic semiconductor based devices for light generation is demonstrated by the commercialisation of display technologies using organic light emitting diode (OLED). In OLED, organic materials plays an ...
Photovoltaic characteristics of hybrid MEH-PPV-nanoparticles compound
(Elsevier B.V., 2013)
Organic solar cell research has vastly developed in recent years. These organic solar cells however are still limited to low power conversion efficiencies. This has led to the generation of photovoltaic cells based on ...
Copper ion-exchanged channel waveguides optimization for optical trapping
(Elsevier Ltd., 2013-08)
Optical trapping of particles has become a powerful non-mechanical and non-destructive technique for precise particle positioning. The manipulation of particles in the evanescent field of a channel waveguide potentially ...
Simulation of Brillouin and Rayleigh scattering in distributed fibre optic for temperature and strain sensing application
(Elsevier B.V., 2013)
This paper presents simulations of a distributed fibre optic sensor for temperature and strain sensing. The behaviours of Brillouin and Rayleigh scattering in optical fibres are studied through the backscatter signals. The ...
Surface modification via wet chemical etching of single-crystalline silicon for photovoltaic application
(Elsevier Ltd., 2013-11)
The potential of solar cells have not been fully tapped due to the lack of energy conversion efficiency. There are three important mechanisms in producing high efficiency cells to harvest solar energy; reduction of light ...
